CVE-2017-12103

An exploitable integer overflow exists in the way that the Blender open-source 3d creation suite v2.78c converts text rendered as a font into a curve. A specially crafted .blend file can cause an integer overflow resulting in a buffer overflow which can allow for code execution under the context of the application. An attacker can convince a user to open the file or use the file as a library in order to trigger this vulnerability.

Updated blender package fixes security vulnerabilities:

Multiple vulnerabilities have been discovered in various parsers of Blender. Malformed .blend model files and malformed multimedia files (AVI, BMP, HDR, CIN, IRIS, PNG, TIFF) may result in the execution of arbitrary code (CVE-2017-2899, CVE-2017-2900, CVE-2017-2901, CVE-2017-2902, CVE-2017-2903, CVE-2017-2904, CVE-2017-2905, CVE-2017-2906, CVE-2017-2907, CVE-2017-2908, CVE-2017-2918, CVE-2017-12081, CVE-2017-12082, CVE-2017-12086, CVE-2017-12099, CVE-2017-12100, CVE-2017-12101, CVE-2017-12102, CVE-2017-12103, CVE-2017-12104, CVE-2017-12105).

These issues are fixed by updating to the latest upstream 2.79b release, which brings many improvements, bug fixes and new features. See the referenced changelog for details.

Also, the yafaray package has been updated to the latest version, 3.3.0, to make it work with the new Blender addons path.
